13 INSTALLATION CONNECTION OF ANTENNA AND POWER SUPPLY The FT-450 is designed for use with any antenna system providing a 50 Ohm resistive impedance at the desired operating frequency. Every effort should be made to ensure the impedance of the antenna system is as close as possible to the specified 50-Ohm value. Note that the G5RV type antenna does not provide 50-Ohm impedance on all HF Amateur bands, and an external wide-range antenna coupler must be used with this antenna type. Any antenna to be used with the FT-450 must, ultimately, be fed with 50 Ohm coaxial cable. Therefore, when using a balanced antenna such as a dipole, remember that a balun or other matching/balancing device must be used to ensure proper antenna performance. CAUTION Permanent damage can result if improper supply voltage, or reverse-polarity voltage, is applied to the FT-450. The Limited Warranty on this transceiver does not cover damage caused by application of AC voltage, reversed polarity DC, or DC voltage outside the specified range of 13.8V ±10%. When replacing fuses, be certain to use a fuse of the proper rating. The FT-450 requires a 25A fastblow fuse.

14 INSTALLATION GROUNDING The FT-450 transceiver, like any other HF communications apparatus, requires an effective ground system for maximum electrical safety and best communications effectiveness. A good ground system can contribute to station efficiency in a number of ways: It can minimize the possibility of electrical shock to the operator. It can minimize RF currents flowing on the shield of the coaxial cable and the chassis of the transceiver. Such currents may lead to radiation, which can cause interference to home entertainment devices or laboratory test equipment. It can minimize the possibility of erratic transceiver/accessory operation caused by RF feedback and/or improper current flow through logic devices. An effective earth ground system may take several forms. For a more complete discussion, see an appropriate RF engineering text. The information below is intended only as a guideline. Typically, the ground connection consists of one or more copper-clad steel rods, driven into the ground. If multiple ground rods are used, they should be positioned in a V configuration, and bonded together at the apex of the V which is nearest the station location. Use a heavy, braided cable (such as the discarded shield from type RG-213 coaxial cable) and strong cable clamps to secure the braided cable(s) to the ground rods. Be sure to weatherproof the connections to ensure many years of reliable service. Use the same type of heavy, braided cable for the connections to the station ground bus (described below). Inside of the station, a common ground bus consisting of a copper pipe of at least 25 mm (1 ) diameter should be used. An alternative station ground bus may consist of a wide copper plate (single-sided circuit board material is ideal) secured to the bottom of the operating desk. Grounding connections from individual devices such as transceivers, power supplies, and data communications devices (TNCs, etc.) should be made directly to the ground bus using a heavy, braided cable. Do not make ground connections from one electrical device to another, and thence to the ground bus. This socalled Daisy-Chain grounding technique may nullify any attempt at effective radio frequency grounding. See the drawing below for examples of proper grounding techniques. Inspect the ground system - inside the station as well as outside - on a regular basis so as to ensure maximum performance and safety. Besides following the above guidelines carefully, note that household or industrial gas lines must never be used in an attempt to establish an electrical ground. Cold water pipes may, in some instances, help in the grounding effort, but gas lines represent a significant explosion hazard, and must never be used.

15 INSTALLATION VL-1000 LINEAR AMPLIFIER INTERCONNECTION Be sure that both the FT-450 and VL-1000 are turned off, then follow the installation recommendations contained in the illustration. Note: Please refer to the VL-1000 Operating Manual for details regarding amplifier operation. Please do not attempt to connect or disconnect coaxial cables when your hands are wet.

If you plan on using multiple linear amplifiers for different bands, you must provide external band-switching of the Lin Tx relay control line from the TX GND OUT line at the LINEAR jack. Important Note! Do not exceed the maximum voltage or current ratings for the TX GND OUT line at the LINEAR jack. This line is not compatible with negative DC voltages, nor AC voltages of any magnitude. Most amplifier control relay systems require only low DC voltage/current switching capability (typically, +12V DC at 25 ~ 75 ma), and the switching transistor in the FT-450 will easily accommodate such amplifiers.

27 CONVENIENCE FEATURES RECEIVER OPERATION (FRONT END BLOCK DIAGRAM) The FT-450 includes a wide range of special features to suppress the many types of interference that may be encountered on the HF bands. However, real world interference conditions are constantly changing, so optimum setting of the controls is somewhat of an art, requiring familiarity with the types of interference and the subtle effects of some of the controls. Therefore, the following information is provided as a general guideline for typical situations, and a starting point for your own experimentation. The FT-450 s interference-fighting circuitry begins in its RF stages, and continues throughout the entire receiver section. FT-450 allows configuration of the features described below. R. FLT (IF Roofing Filters) The Roofing filter, with a bandwidth of 10 khz is provided in the 68 MHz First IF, right after the first mixer. This filter provides narrow-band selectivity to protect the following IF and DSP stages, for special operating circumstances. CONTOUR Filter (SEE PAGE 28) The DSP Contour filter provides a unique capability on the receiver, providing either nulling or peaking of tunable segments of the receiver passband, so as to suppress interference or excessive frequency components on an incoming signal, or to peak those tunable frequency segments. The amount of nulling/ peaking, and the bandwidth over which it is applied, are adjustable via the Menu. IF SHIFT (SEE PAGE 29) The passband center frequency response of the IF DSP filtering may be adjusted using this control. IF NOTCH (SEE PAGE 31) The IF Notch filter is a high-q notch filter that can significantly reduce, if not eliminate, an interfering carrier. DNR (DIGITAL NOISE REDUCTION) (SEE PAGE 32) The DSP s Digital Noise Reduction (DNR) feature utilizes eleven different mathematical algorithms to analyze and suppress different noise profiles encountered on the HF/50 MHz bands. Choose the selection that provides the best noise suppression, which concurrently will allow the signal to rise up out of the noise. AGC (SEE PAGE 27) The AGC system is highly adaptable to changing signal and fading characteristics, making reception possible under the most difficult conditions. IF WIDTH (SEE PAGE 30) The width of the IF DSP filtering may be adjusted using this control. Page 25

28 CONVENIENCE FEATURES ATT/IPO (ADJUST THE RECEIVING SENSITIVITY) You may reduce the receiving signal strength to 20 db when extremely strong local signals or high noise degrade reception. You may optimize the characteristics of the receiver front-end, for best reception, depending on the noise levels and the signal strengths. Press the [ATT/IPO] button several times to set the desired selection, per the chart below. ATT: OFF, IPO: OFF Attenuator is OFF, and the incoming signal is amplified by the RF preamplifier. ATT: ON, IPO: OFF ATT: OFF, IPO: ON Attenuator is ON, (the incoming signal is reduced by 20 db) and the incoming signal is amplified by the RF preamplifier. Attenuator is OFF, and the incoming signal bypasses the RF preamplifier, yielding direct feed to the first mixer. [ATT/IPO] button Block Diagram ATT: ON, IPO: ON Attenuator is ON, (the incoming signal power is reduced by 20 db) and the incoming signal bypasses the RF preamplifier, yielding direct feed to the first mixer. The selection will be indicated in the Block Diagram on the display. NOTE An attenuator is always ON between 30kHz and 1.7MHz. NOISE BLANKER (INTERFERENCE REJECTION SIGNALS WITHIN 3 KHZ ) The FT-450 includes an effective Noise Blanker, which can significantly reduce noise caused by automotive ignition systems. 1. Press the [NB] button to activate the Noise Blanker. 2. Press the [NB] button again to disable the Noise Blanker. The selection will be indicated in the Block Diagram on the display. [NB] button Block Diagram Page 26

29 AGC (TOOL FOR COMFORTABLE AND EFFECTIVE RECEPTION) The AGC system is designed to help compensate for fading and other propagation effects, with characteristics that can be of particular value on each operating mode. The basic objective of AGC is to maintain a constant audio output level once a certain minimum threshold of signal strength is achieved. Press the [AGC] button repeatedly to select the desired receiver-recovery time constant. The AGC status is indicated in the Block Diagram displayed on the display. For most operations, we recommend the AUTO mode. You may disable the AGC by pressing and holding in the [AGC] button for one second. CONVENIENCE FEATURES AUTO Sets the receiver-recovery time automatically depending on the operating mode. FAST SLOW Sets the receiver-recovery time to fast. This mode is suitable for CW/DATA reception. Sets the receiver-recovery time to slow. This mode is suitable for SSB/AM reception. [NB] button Block Diagram NOTE: Normally, the AUTO selection is satisfactory for most situations, but in the event of operation on a crowded band where you wish to receive a weak signal, you may wish to change the setting (to FAST, for example). The AUTO mode selections are: OPERATING MODE LSB USB CW AM FM DATA AUTO AGC SELECTION SLOW SLOW FAST SLOW FAST (Fixed) FAST ADVICE: If the AGC receiver-recovery time is set to Off by pressing and holding in the [AGC] button, the S-meter will no longer deflect. Additionally, you will likely encounter distortion on stronger signals, as the IF amplifiers and the following stages are probably being overloaded. Page 27

30 CONVENIENCE FEATURES CONTOUR (INTERFERENCE REJECTION SIGNALS WITHIN 3 KHZ ) The Contour filtering system provides a gentle perturbation of the IF filter pass band. so as to suppress or enhance particular frequency components in five steps, thus improving the sound and/or readability of a received signal. 1. Press the [DSP] button several times to set the > icon to the CONTOUR indicator of the DSP Graphic Display on the display. 2. Press the [DSP/SEL] knob to engage the contour filter. 3. Press and hold the [DSP/SEL] knob for one second to toggle the contour filter s level between null and peak. 4. Rotate the [DSP/SEL] knob to achieve the most natural-sounding audio reproduction on the incoming signal. The peak position of the contour filter is graphically-depicted in the CONTOUR indicator of the DSP Graphic Display on the LCD. 5. Press the [DSP/SEL] knob again to increase the contour filter s level ( null or peak ). 6. To disable the contour filter, press the [DSP/SEL] button again. The graphic disappears from the CONTOUR indicator of the LCD Display, confirming that the contour filter is no longer operating. CONTOUR NULL CONTOUR PEAK CONTOUR OFF CONTOUR GAIN LOW CONTOUR Indicator [DSP/SEL] knob [DSP] button Refer to Figure B, this shows a indentation of the contour filter is center of a passband. Counter-clockwise rotation (to the left) of the [DSP/SEL] knob causes the indentation to move toward a lower frequency within the passband, while clockwise rotation (to the right) causes the indentation to move toward a higher frequency within the passband. By removing interference or unwanted frequency components on the incoming signal, it is possible to make the desired signal rise out of the background noise/interference, enhancing intelligibility. A B C CONTOUR NULL CONTOUR PEAK CONTOUR OFF CONTOUR GAIN HIGH IF IF IF BANDWIDTH BANDWIDTH BANDWIDTH DSP/SEL DSP/SEL DSP/SEL QUICK POINT: The steep slopes of the DSP filtering can, when adjusted aggressively, impart an unnatural sound to an incoming signal. Often, a narrow bandwidth is not the key to improving copy. The incoming signal itself may have undesirable or excessive frequency components. By judicious use of the Contour filter, the shoulder of the passband response may be altered, or components removed from within the passband, allowing the desired signal to rise above the background noise and interference in a manner not obtainable with other filtering systems. Page 28

31 CONVENIENCE FEATURES SHIFT (INTERFERENCE REJECTION SIGNALS WITHIN 3 KHZ ) IF Shift allows you to vary the DSP filter passband higher or lower, without changing the pitch of the incoming signal, so as to reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is no need to re-tune the operating frequency when eliminating the interference. The total passband tuning range for the IF Shift system is ±1 khz. Rotate the [SHIFT] knob to the left or right to reduce the interference. SHIFT Indicator You may observe the position of the passband in the SHIFT indicator of the DSP Graphic Display on the display. [SHIFT] KNOB FULLY COUNTER-CLOCKWISE [SHIFT] KNOB 12 O CLOCK POSITION [SHIFT] knob [SHIFT] KNOB FULLY CLOCKWISE Referring to Figure A, note the depiction of the IF DSP filter as the thick line, with the [SHIFT] knob in the 12 o clock position. In Figure B, an interfering signal has appeared inside the original passband. In Figure C, you can see the effect of rotating the [SHIFT] knob to reduce the interference level by moving the filter passband so that the interference is outside of the passband.

32 CONVENIENCE FEATURES WIDTH (INTERFERENCE REJECTION SIGNALS WITHIN 3 KHZ ) The IF Width tuning system allows you to vary the width of the DSP IF passband with three steps (FM: two steps), so as to eliminate interference. Moreover, the bandwidth may actually be expanded from its default setting, should you wish to enhance incoming signal fidelity when interference on the band is low. 1. Press the [DSP] button several times to set the > icon to the WIDTH indicator of the DSP Graphic Display on the display, to enable adjustment of the bandwidth by the [DSP/SEL] knob. 2. Rotate the [DSP/SEL] knob to adjust the bandwidth. Counter-clockwise rotation reduces the bandwidth, while clockwise rotation increases the bandwidth. WIDTH Indicator [DSP/SEL] knob [DSP] button Referring to Figure B, this is default bandwidth. By rotating the [DSP/SEL] knob to the left, the bandwidth will narrow (see Figure A, while rotation of the [DSP/SEL] knob to the right, as depicted in Figure C, will widen the bandwidth. A B C IF BANDWIDTH DSP/SEL IF BANDWIDTH DSP/SEL IF BANDWIDTH DSP/SEL The default bandwidths, and total bandwidth adjustment range, will vary according to the operating mode: SSB Mode: 1.8 khz / 2.4 khz / 3.0 khz (Nominal: 2.4 khz). CW Mode: 500 Hz / 1.8 khz / 2.4 khz (Nominal: 1.8 khz). AM Mode: 3.0 khz / 6.0 khz / 9.0 khz (Nominal: 6.0 khz). FM Mode: 2.5 khz / 5.0 khz (Nominal: 5.0 khz). Using IF Shift and Width Together The IF Shift and Variable IF Width features together form a very effective interferencefighting filtering system. For example, in Figure A you can see how interference has appeared both on the high and low sides of the desired signal. By rotating the [DSP/SEL](WIDTH) knob, as shown in Figure B, the interference from one side can be eliminated, and by re-positioning the [SHIFT] knob (Figure C ), the interference on the opposite side can be removed, without re-introducing the interference previously eliminated in Figure B. Advice: For best interference reduction, the Width and Shift features are the primary tools you should use. After narrowing the bandwidth (Width) and/or adjusting the center of the passband (Shift), the Contour control may also yield additional signal-enhancement benefits on the net residual bandwidth. What s more, the IF Notch Filter (see the next section) may also be utilized, in conjunction with the three other filter systems, to significant advantage.

33 CONVENIENCE FEATURES NOTCH (INTERFERENCE REJECTION SIGNALS WITHIN 3 KHZ ) The IF Notch filter is a highly effective system that allows you to slice out an interfering beat note or other carrier signal from inside the receiver passband. 1. Press the [DSP] button several times to set the > icon to the NOTCH indicator of the DSP Graphic Display on the display. 2. Press the [DSP/SEL] knob to engage the IF Notch filter. 3. Rotate the [DSP/SEL] knob to adjust the center frequency of the IF Notch Filter. You may observe the graphically depicted peak position of the IF Notch filter in the NOTCH indicator of the DSP Graphic Display on the display. 4. To disable the IF Notch filter, press the [DSP/SEL] button again. The graphically depicted peak position disappears from the NOTCH indicator of the DSP Graphic Display on the display confirming that the IF Notch filter is no longer operating. NOTCH Indicator [DSP/SEL] knob [DSP] button The performance of the IF Notch filter is shown in Figure A, where the effect of rotation of the [DSP/SEL] knob is depicted. In Figure B, you can see the notching effect of the IF Notch filter as you rotate the [DSP/ SEL] knob to eliminate the incoming interference.

34 CONVENIENCE FEATURES DNR (INTERFERENCE REJECTION SIGNALS WITHIN 3 KHZ ) The Digital Noise Reduction (DNR) system is designed to reduce the level of random noise found on the HF and 50 MHz bands, and it is especially effective during SSB operation. Any of eleven different noise-reduction algorithms can be selected. Each of these algorithms was created for dealing with a different noise profile, and you will want to experiment with the DNR system to find the best setting according to the noise currently being experienced. 1. Press the [DSP] button several times to set the > icon to the DNR indicator of the DSP Graphic Display on the display. 2. Press the [DSP/SEL] knob to engage the Digital Noise Reduction system. 3. Rotate the [DSP/SEL] knob to select the setting that most effectively reduces the noise level. You may observe the effectiveness of the Digital Noise Reduction system in the DNR indicator of the DSP Graphic Display on the display. 4. To disable the Digital Noise Reduction system, press the [DSP/SEL] button again. The graph effectively disappears from the DNR indicator of the DSP Graphic Display on the display confirming that the IF Notch filter is no longer operating. DNR Indicator [DSP/SEL] knob [DSP] button Page 32

35 RF GAIN The RF Gain controls provide manual adjustment of the gain levels for the receiver RF and IF stages, to compensate for noise and/or signal strength conditions at the moment. The [SQL/RF GAIN] knob should, initially, be rotated to the fully clockwise position. This is the point of maximum sensitivity, and counter-clockwise rotation will gradually reduce the system gain. CONVENIENCE FEATURES ADVICE: As the [SQL/RF GAIN] knob is rotated counterclockwise to reduce the gain, the S-meter reading will rise. This indicates that the AGC voltage being applied to the receiver is increasing (which causes a reduction in receiver gain). Rotating the [SQL/RF GAIN] knob control to the fully counter-clockwise position will essentially disable the receiver, as the gain will be greatly reduced. In this case, the S-meter will appear to be pegged. (That is a full-scale reading). [SQL/RF GAIN] knob Page 33

74 RTTY (RADIO TELETYPE) OPERATION Most RTTY operation today is accomplished using a TNC or other computer-based system that utilizes AFSK tones. For RTTY operation using a Terminal Unit (TU) or the FSK output from a TNC, please see the discussion below. See also the illustration for details regarding connection to your TU. INPUT DC 13.8V 22A ANT DATA TUNER LINEAR CAT EXT SPKR GND FSK OUT AF IN PTT DATA PTT DATA OUT FSK IN GND DATA JACK DATA IN (Pin 1) GND (Pin 2) DATA PTT (Pin 3) FSK IN (Pin 4) DATA OUT (Pin 5) SQL OUT( Pin 6) TU N.C. GND PTT FSK OUT AF IN N.C. Before commencing RTTY operation, please direct your attention to the setup steps shown in the chart to the right. SETTING UP FOR RTTY OPERATION MENU ITEM RTY SFT (RTTY SHIFT) RTY TON (RTTY TONE) RTYRPOL (RTTY RX POLARITY) RTYTPOL (RTTY TX POLARITY) AVAILABLE VALUES 170 / 200 / 425 / 850 Hz 1275 / 2125 Hz NOR / REV NOR / REV 1. Press the [MODE ]/[MODE ] buttons several times to indicate both the and icons on the display. Engage the RTTY operation using LSB injection, which is generally used in the Amateur service. 2. When you begin typing on your TU or computer keyboard, the command to transmit should automatically be sent to the transceiver, causing it to enter the transmit mode. NOTE: If you anticipate making data transmissions of longer than a few minutes, we recommend that you reduce the transmitter power to 1/2 ~ 1/3 of its normal maximum via Menu Item RFPOWER. QUICK POINT: In the FT-450, RTTY is a mode defined as being an FSK mode, whereby the closing and opening of a keying line (to ground) causes the Mark/Space tones to alternate. The RTTY mode is not an AFSK based mode in this transceiver, and the AFSK output tones from a TNC will not cause Mark/Space shifting to occur. Use the Packet mode for AFSK-based Baudot and other data modes. BASIC SETUP ADVICE: There is no adjustment of the FSK input level (FSK IN of the DATA jack) on the rear panel; please make any needed level adjustments at the TU side. The Mark/Space Shift utilized in most Amateur RTTY operation is 170 Hz. Other shifts may be configured, however, using Menu Item RTY SFT. The FT-450 is set up for high tone operation (centered on 2125 Hz) by default, but you may configure it for low tone (1275 Hz) operation using Menu Item RTY TON. You may find that you are unable to decode some RTTY stations, even if they are of sufficient signal strength. If this is observed, there may be a Mark/Space polarity problem between your station and the other station. If so, try setting Menu Item RTYRPOL to REV ( Reverse ) to see if that permits copy. A separate Menu Item permits reversal of your transmitter s Mark/Space polarity: RTYTPOL. Page 72

75 PACKET OPERATION Packet operation is easily accomplished on the FT-450 by connecting your TNC (Terminal Node Controller) to the transceiver, per the illustration.

PACKET SETUP (INCLUDING SUBCARRIER FREQUENCY) Before operation can commence, change Menu Item D TYPE setting to USER-L (for LSB-Based Packet Operation) or USER-U (for USB-Based Packet Op- eration), to configure your radio for the data mode to be used. 1. Press the [MODE ]/[MODE ] buttons several times to indicate both the and icons (for LSB-Based Packet) or the and icons (for USB-Based Packet) on the display. Engage the Packet operation. 2. When the transmit command is received from the TNC, the transmitter of the FT-450 will automatically be engaged. Likewise, the command to return to receive will cause the radio to revert to the receive mode. ADVICE: There is no adjustment of the DATA input level and DATA output level of the DATA jack on the rear panel; please make any needed level adjustments at the TU side. During Packet operation via the rear panel s DATA jack, the front panel MIC jack is cut off, so you won t have a live microphone problem during data operation. BASIC SETUP NOTE: If you anticipate making data transmissions of longer than a few minutes, we recommend that you reduce the transmitter power to 1/2 ~ 1/3 of its normal maximum via Menu Item RFPOWER.
